概要	A Mobile Research Diary is a data collection technique in which participants record thoughts, experiences, behaviours, or events in structured diary entries submitted via a smartphone or tablet app over a defined study period. By moving the diary onto a mobile device, researchers gain time-stamped, geolocation-optional data captured close to the moment of experience, reducing retrospective recall bias while maintaining the rich, naturalistic quality of traditional diary methods.	A research diary is a systematic, dated log maintained by the researcher throughout a study to record methodological decisions, emergent observations, analytical hunches, and reflections on researcher positionality. Unlike a participant diary, it is authored by the researcher and functions simultaneously as a data source, an audit trail, and a reflexivity instrument.
